     Lcr Rate Multiplier
         Value of this field (numeric) is used during building of Dialpeers rating (sorting of Dialpeers) for routing call on the basis of least-cost routing (LCR). This value is used for multiplying :ref:`Next Rate <dialpeer_next_rate>` value only during building of Dialpeers rating and doesn't effect on final cost of call.
